provements in Engine Self-Oiling Mechanism;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the'art lto which it appertains to make and use theY same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to engine self-oiling mechanism,and is designed as an improvement on the oiling apparatus patented to me in my United States Letters Patent No. 640,422, dated January 2, 1900; and it consists, substantially, in a construction of oiling apparatus adapted to supply oil through suitable discharge-openings in a transverse pipe above the cross-head guides, so as to not only lubricate the guides, but to dischargeoil into channels in the top of the engine-frame leading to the bearing of the main shaft of the engine, the surplus oil being discharged from the shaft-bearings to the crank-pin in the usual manner, and after it has lubricated the guides, shaft-bearings, and crank-pins it passes into a chamber in the engine-frame and is discharged therefrom into a filtering-tank, from which it is again supplied to the engine, as beforei Another feature of invention relates to means for operating the oil-pump forming part of my apparatus by means of mechanism engaging the cross-head within the engineframe, whereby the pump is operated.

The features of my invention are hereinafter fully set forth and explained, and illustr'ated in the accompanying drawings, in which- Figure l is a side View in elevation of an engine embodying my'invention. Fig. 2 is a top or, plan view of the engine-frame with the cover thereof removed. Fig. 3 is a side view of the same, partially in elevation and partially in section. Fig. 4 is a transverse section of the same on the line a in Figs. l and 3 looking inthe direction of the arrow.

In the drawings, A is an engine-frame; B, the cylinder; C, thev fly-wheel; C, the main shaft; C, the shaft-boxes; D, the cross-head guides, and E the filtering-tank, all of the usual construction except as to certain' fea.- tures hereinafter described in the engineframe.

rI he oil-pump F, forming part of my device, I

is preferably of the rotary type and is secured to 'the side 'of the engine-frame A, andthe operating-shaft f thereof passes through an opening in the side of the engine-frame and is provided with a crankf, which engages a diagonal slot g in the side of the cross-head Gr, so that thereciprocal movement of the cross-head G operates to rotate the pumpshaft f back and forth, so as to operate the v pump-piston.

A suction-pipe H connects the pump F with a filter-tank E in the usual manner, and a pipe H also extends upward to an overowtank H2 in the usual manner. An overflow-pipe 7L is also provided to carry the surplus oil pumped back into the tank E, the pump F and its connections being of the usual construction except as to its operating mechanism hereinbefore described.

Across the top of the engine-frame A, I secure a transverse pipe J, hinged by means of a hollow joint j to a hollow standard J', so that it can be raised up out of the way. hollow standard J is connected by a pipe /L with the pump F. so that oil will fiow freely from the pump F into the pipe J. In this pipe J, I secure suitable oil-discharge devices K, provided with regulating devices awhereby the discharge of oil therefrom can be regulated. In the top of the engine-frame A, I make grooves or channels a a, which incline and lead back toward and terminate in pipes a a'. (Clearly shown in Figs. 2and The pipes/Zo a' extend over the oil-openings c in the main-shaft boxes C2. 'Iwo of the oil-discharge devices K discharge oil through openings CZ in the upper of the cross-head guides D u pon the cross-head G operating therein so as to lubricate it, and two of the oil-discharge devices K The discharge oil into the grooves or channels a a in the engine-frame A, along which it Hows until it passes out of the pipes c c into the journal-boxes C2 C2. The oil supplied to the cross-head guides and lubricating them, as well as the oil supplied to and lubricating the journal -boXes C2 C2 and which passes on therefrom to the crank-pin in the usual manner, upon being thrown therefrom collects in the chamber A/ in the engine-frame A and passes out therefrom through a drain-pipe I into the filter-tank E to be filtered and pumped back therefrom, as before.

I have not shown or described theinechanism for conveying oil from the journal-boxes to the crank-pin, as that feature is old and in common use.

Having thus described my invention, so as to enable others to construct and use the same, what I claim as new, and desire to secure by Letters Patent of the United States, is'-w l. An engine self-oilingmeehanism,eonsist ing substantially of an engine-frame having grooves or channels therein communicating with the main-shaft boxes of the engine,an oilpump, mechanism for operating the oil-pum p, a pipe mounted transversely over the crosshead guides of the engine communicating with said pump, and oil-discharging devicesin said pipe for supplying oil both to the cross-head guides and to the grooves or channels in the engine-frame leading to the main-shaft boxes, substantially as set forth.

2. In an engine self-oiling mechanism, an engine-frame having grooves or channels in the upper part thereof, communicating with the main-shaft boxes of the engine, and also having an oil-receiving chamber therein, an oil-pump mounted on said frame, mechanism for operating said oil-pump, a pipe pivotally mounted transversely over the cross-head guides of the engine and communicating with said pump, oil-discharge devices in said pipe, for supplying oil to the cross-head guides and for supplying oil to the grooves or channels in the engine-frame, means for regulating the flow of oil from said oil-discharge devices, a filtering-tank, a pipe connecting the same with the oil-receiving chamber in the engine-frame, and a pipe leading from said filter-tank to said pump, substantially as set forth.

3. In an engine self-oiling mechanism, an engine-frame having oil-chan nels in the frame leading to and communicating with the box or boxes of the main shaft of the engine,cross head guides mounted on said engine-frame, and means for automatically .supplying oil to said channels in the engine-frame substantially as set forth.

4. vIn an engine self-oiling mechanism, an

lengine-frame having a chamber therein,eross head guides mounted within said chamber, a erosshead mounted and operati ng in said guides having a diagonal groove or slot in one side thereof, an oil-pump mounted on the engine-frame and mechanism connecting said pump with the groove in said cross-head for operating the same, substantially as set forth.

In an engine self-oiling meehanism, an engineframe having grooves or channels therein leading from a point near the crosshead guides to the n'iain-shaft boxes, a transverse pipe mounted above the cross-head guides, having oil-discharge openings therein for supplying oil to the cross-head guides and to said channels, and means for supplying oil to said pipe, substantially as set forth.

In testimony whereof I aliix my signature in presence of two witnesses.
